Synthesis Of Quasi-one-dimensional SnO₂ Nanomaterials And Spectrum Performance

Nanoscience and technology is the science of designing and manipulating materials at the level of nanoscale. It emerged in the later half of 1980s and is growing quickly. Nanostructured materials exhibit novel physical and chemical properties and phenomena. Among of nanomaterials, nanoscale one-dimensional (1D) structures such as nanowire, nanorod and namotube are more important because of their great potential for testing and understanding fundamental concepts and application. Sn02 was researched many years ago and used extensively in the conductors. The syntheses and researches of SnO₂ nanorods will help to understand fundamental physical principle of 1D semiconductors and magnetic materials and contribute to the development and application of them.This paper is about fabricating nanostructure of SnO1 in Chemical Vapor deposit. Active carbon and SnO2 powders are mixed and deoxidized at 950℃. We prepared SnO₂ nanonods, nanowire with Vapor-Solid growth mechanism on the Au covered Si substrate. In addition, we adulterate ZnO to SnO₂ and compare their shape. This paper systematically studied the effects of growth mechanism of nanorods. Characterizations of the products by SEM,TEM,SAED, EDS and Raman spectrum showed that SnO₂ nanonords were of purity and rutile lattice structure ,but there are oxygen vacancies. We can use Lamb's theory to explain the Roman Spectrum.
